Receive poll demand register
| RPD | Receive poll demand This register field can be read by the application, and when a write operation is performed with any data value, an event is triggered. When these bits are written with any value, the DMA reads the current descriptor pointed to by the Current Host Receive Descriptor register (Section 26.6.38). If that descriptor is not available (owned by Host), reception returns to the Suspended state and bit 7 in the DMA_STAT Register is not asserted. If the descriptor is available, the Receive DMA returns to active state. |
